Layton Michael R, Bunn James S: A demodulator circuit for an interferometer type of hydrophone. Litton Systems, May 4, 1989: GB2209221-A (132 worldwide citation)

The optical signal in a fiber optic interferometer (20) is phase modulated to provide a carrier signal for phase changes caused by changes in a physical parameter such as sound, being sensed. The signal is then demodulated to measure changes in the parameter. A crystal oscillator (52) frequency refe ...
